Internet radio and audio file player on ESP32-S3

It's cool that you're working something individually with the code, I'd steal something from you later. For now I'm going my own way, today I coded and updated the file player:
- entering the menu by holding down encoder button 1 for 3 seconds,
- then wheel to select "File player" and confirm with encoder button 1,
- the contents of the main folders of the card are listed and the first file of the first folder is played,
- using the encoder wheel you can choose which folder you want to play next
- from mp3 files the ID3 metadata is displayed quite correctly, I attach pictures
In the flac files I have to do ID3 chunking, because they are printed quite differently on the serial than from mp3, the creator of the audio library also seems to have a big mess in it.
In general, I still plan to use the encoder wheel to freely select No. 1 files from the directory similarly listed as radio stations from the bank.

.


When I go to the folder with the flac files, it resisted starting:
.

That's enough for today:
.

From the series of what I did for my radio today

- I improved the exit from any sub-menus
The function "if (displayActive && (millis() - displayStartTime >= displayTimeout)) " is supposed to exit to the main screen but ....
It does this incorrectly. If we enter the BANK selection menu and we don't select anything (by turning the encoder or not), then, unfortunately, when we return by turning the station selection - we select from the BANK on which we left the indicator "bank_nr". In other words you have to remember the variable bank_nr = previous_bank_nr; so that you always come back with the correct value of bank_nr. I hope I didn't confuse things too much.

in addition:
- I introduced sliders/progress bars for the volume control menu and the bank menu. Eventually there will be an Update option in the bank selection: "NET" - "SD card"
- slider in the bank selection menu
- fix (described above) to return correctly from the bank selection menu
- for beautification I added an icon and information if we cannot initialise the card, because it has become an important element holding the radio data
- I trimmed the station name to 26 characters
- I have created a template in excel for preparing the memory bank files

MAJSTER XXL Code as much as possible to make available for everyone. Take what you will need. I think I'll set up a GitHub to upload it there

I uploaded the latest compilation with the player today as a test.
Unfortunately it still works very capriciously, long file names don't work, it doesn't open flac files, mp3 also very selectively.
Stubbornly wants to play from the folder "System Volume Information" to the selection of folders with space also does not suit it.

It is a -> very very early pre-beta release - I would call it .

For handling ID3 TAGs, I guess it will be worth implementing the "u8g2 text scroll" function to make it scroll nicely. I'll sit down to do that in my spare time.
Now it's time to design the mount for the OLED and print it out. This mess of a circuit board needs to be sorted out.

@robgold Interesting, I don't have this problem with System Volume- it is skipped. I have spaces in all my folder names and it works normally, so I don't understand why it's happening to you- it's not by chance the fault of a substituted font?
I have over 60 folders on my card and all the mp3s with different bitrates play correctly. I just have to figure out the right moment to put the audio file data on the display, because if I put it too early it sometimes shows up with some rubbish.
I also don't understand why it doesn't nicely display a selected folder in a rectangle - just like a radio station - even though the function for scrolling and displaying folders has the same settings as for scrolling through radio stations. The flac files from my card play normally.
The fact that I already had the so-called previous bank and station number in the first version of the radio, but here apparently variables were declared, but I did not assign them later - it escaped me. Yesterday, when I was working on the file player, I had the same situation with the previous folder and file numbers, so that after turning the wheel but without confirming them, they returned to the correct numbers - I have that covered.
.

Master , to test what cool stuff you've done in the code I always upload your entire original file to ESP. Only then I copy myself what I like there .

As for the font and selection highlighting problem.
I've had a look at the code and the problem lies in the incorrect jumping and painting of this frame. The Spleen font we are using is called Spleen6x12 but it actually has 6 boxes in the x axis and 13 in the y axis. Take a peek at the screenshot from the Fony program I use to edit fonts.
It purposely shows the little 'y' because it is one of the critical ones that just uses the fields below the tenth i.e. it uses 11,12 and 13 to display the tail.

In the station listing section this is also incorrectly done, but as the list fills the whole screen and the font is of type mr (not tf which means transparent) each subsequent line cuts out 1 selection pixel and you can't even see it. Take a look at the attached screenshot.

In order to correctly display the selection in the code section below, you must always jump 13 boxes. That's why I changed the multiplier value to 13. The -2 and +8 offsets are just cosmetic to start writing as high as possible to make the last line of the list look decent because 64 does not divide by 13.

// Limit the length to 42 characters
String displayedPath = fullPath.substring(currentDirectory.length(), currentDirectory.length() + 42);

// Highlight the selected directory
if (i == currentSelection)
{
u8g2.setDrawColor(1); // White background colour
u8g2.drawBox(0, displayRow * 13 - 2 , 256, 13); // Draw a rectangle as the background for the selected folder
u8g2.setDrawColor(0); // Black text colour
}
else
{
u8g2.setDrawColor(1); // White text colour on black background
}

// Display path
//u8g2.setCursor(0, displayRow * 10 + 10); // Set the cursor for the line in question
//u8g2.print(displayedPath); // Display directory name

u8g2.drawStr(0, displayRow * 13 + 8 ,String(displayedPath).c_str());
// Move to the next row
displayRow++;
}

Going back to the player topic I have corrected two things:
You are indexing the folders from 1 while the listing starts in the array from 0. Since we already have a variable of type Int with a sign, in order to "catch" the first folder you need to count from 0 and change in the code to replace the value of <0 (was <1) with 0. Otherwise we will lose the folder with indexing [0].

if (digitalRead(DT_PIN2) == HIGH)
{
folderIndex--;
if (folderIndex < 0)
{
folderIndex = 0;
}
Serial.print("Backward folder number: ");
Serial.println(folderIndex);

I also analysed why my folder with FLAC files wouldn't play and it turned out that trimming the names causes the path to the files to be lost.
It just so happened that I put the folder [Varius Manx -Z Zanim Zrozumiesz (Złota Kolekcja)] into the test, which in the terminal resulted in the
Varius Manx -Zanim Zrozumiesz (Złota Kolekcja)], which in the terminal results in clipping the name to [Varius Manx -Zanim Zrozumiesz (Złota Kolekcja)] and because this clipped name then takes an active part in assembling the path to the file, the player cannot find the correct file.

eof_mp3 01 - Varius Manx - Moonlight Song.flac
info End of file "01 - Varius Manx - Piosenka księżycowa.flac"
File playback: 2/3 - 02 - Varius Manx - Before you understand.flac
info buffers freed, free Heap: 231616 bytes
info ERROR: File doesn't exist: / Varius Manx -Zanim Zrozumiesz (Zł /02 - Varius Manx - Zanim zrozumiesz.flac

And besides:
I made myself a cool welcome screen .
I designed a frame for the display, which will eventually be the base for the case.
In the v6 version, I raised the bezel-display distance to 3.8mm (according to the datasheet it is 2.8mm but that doesn't match reality)

I am attaching the 7z file - inside the SKP file (from the online version of SketchUp) and the STL to print out

You've got it covered nicely, I've also thrown in a lot of changes today, I've grouped some repetitive code into void functions, it's all started to work much better, I'm currently focusing my attention on the file player so that the artist and title info is pulled from the printed info on the series instead of digging around and changing the Audio library to suit myself. I have made it so that when there are no ID3 tags, the file name is displayed. In general I've noticed that the Audio library has a problem displaying the bitrate of flac files from the file player correctly. Test my player if you can. I still need to refine the menu for selecting and exiting the Radio / Player function. I was also thinking of a separate menu command like update banks, all at once, so that I'm not constantly downloading and saving them to the card. Thanks for directing me to the actual font size and the needed field size for the highlight. Since the lowercase 'g' was displaying correctly before, I thought the lowercase 'y' was that without the lower horizontal tail, and it is indeed lowered.
Fact, I'll still check the clipping of the name which is then taken for the pathname, I just had short folder names and didn't notice that - thanks for the good point.

@robgold
Hi. I've been following your revisions to the project diligently and it looks like, like the author, you are in control of what you are doing. This is a good thing, because as I can see the project has potential.
However, I couldn't find attached to the post, the display frame design files.
You also mentioned that you'd probably set up a github account for yourself, which would make it a lot easier to make any changes and corrections and keep your branch of the project in check.
If this is up to date, please set up said account and share this information with us.

Once again, great respect to the Author @MAJSTER XXL and to you for developing this worthy project.
I'm keeping my fingers crossed as I also intend to build this radio.

@Andrzej Ch.. .

Actually, I don't know for what reasons the 7z attachment didn't add properly.
When it comes from GitHub I even already tried the first approach but some "yeggold" took the name "Robgold" from me to that nothing has been published for many years. I even had the suspicion that maybe it was me, but unfortunately none of the email addresses I have matched the password recovery and not having an account makes it impossible to suspect the owner's email .
I was thinking of another name, until something distracted me during the Christmas break and, of course, I did not create an account.... but I promise to make up for it by the end of the weekend!

@MAJSTER XXL
Today I sat down and "ported" the player code to my compilation. This is probably the hardest thing for anyone to do.
To copy with relative understanding code that you didn't write yourself .

Just as a quick aside, the Volume Information problem continues. Despite bypassing the folder "System Volume Information" it is still in the indexing by which an empty selection is created because the index is then used as if (i == currentSelection) etc....

A solution might be to move all the music to the "music" folder on the card and only look for it there. This will keep the relative order on the card's main path. Option two would be to try to pose "traps" when "String fullPath = directories[ i ];" will have an index corresponding to the System Volume Information skip it index for highlighting. Just does it make sense to dummy up and predict all cases ?
I will test further. Something I will probably still find .

I will add from myself:
I have changed the player screen and at the moment when there is no ID3Tag I cut out the name and title according to the scheme Artist - Title.mp3 because this is how I always "rip" CDs to the digital collection. Finally, since we have a graphic OLED, let's take advantage of its possibilities.

At the moment I have made an enclosure design based on aluminium profiles (there are no aluminium profiles on the market or I haven't found any) for a large 160x160 enclosure with a height of 40mm (the 3.12 display requires a minimum of 35mm). Ultimately I want to move to a 2 inch display and Hammond 1455R1601BK case which is 30mm.

As soon as I have printed and tested the new enclosure I will upload the files here.
As you can see the front panel is still in the 'alpha' version.

I've today added alphabetical sorting when listing folders, as adding more to the card put them mostly at the end and the order was non-existent. I'm still working on getting rid of the System Volume Information so it doesn't list. By the way, I've made the fixes you suggested, although not everything yet, but it's working quite nicely already. I encourage those who are watching to make a kit like this for themselves to start with on a simple contactor, because it's fun. Now, during the winter, I still have the desire to work on it in the evenings, but from the spring I will have less time for it, so maybe my colleagues will polish this project more.


.

I managed to print a prototype of the case. As it is in a prototype there are many things to improve but it promises to be good.
On the front panel the card reader has to be moved, because on the left side there will be a physical switch and on the right a microSD card plus two encoders.

@MAJSTER XXL .

I have added a lot of cosmetics in the player itself:
- for a file without id3tag I put together a description from the name of the file itself
- fonts, screens
- I threw out the Bank selection case from the menu - a remnant probably from version 1 of the radio, which caused one unnecessary click with the encoder
- still in a few places I caught the entry folderIndex=1 instead of folderIndex=0
- I changed: //listDirectories("/music"); -> listDirectories(currentDirectory.c_str()); so that the path can be manipulated in one place in the variable declarations
- I moved all the music to the /music directory

Here a moment of description. I replaced the currentDirectory path and corrected the variable:
folderNameString = directories[folderIndex]; -> folderNameString = currentDirectory + directories[folderIndex]; .

Curiosity:
somewhere when setting the path to the card's main folder it does a double slash. It works because the SD library is immune to
this type of entry -> //. Despite a lot of fine-tuning as you can see on the serial with the name "Debug" I didn't catch where this is added.
Perhaps you can find it before I get to it. If you type currentDirectory = "/music" instead of "/" the problem goes away.

debug--FolderNameString: //Happysad -Unhappy
debug--fileName: 01 - Happysad - Mileowy Las.flac .

Am I the only one who is slowly starting to be "bothered" by the lack of left-right, up-down, OK buttons in the middle ? I have the impression that it is becoming increasingly difficult to have such an extensive device on 2 encoders and 2 buttons.

I miss a bit of revision of the next releases of the ino file from your side.
I know it is "alive" all the time but it would be easier to follow the changes. Could you introduce something like this? e.g. naming the file after the insertion date?

Plans and dreams or such a small "ToDo" list from my side:
- unify the language either EN or PL because now there is a Volume and a player in Polish
- scrolling of the text on the display and replacement of all those case selections with long artist or song or file names
- track to music stored on SD card
- configuration kept on SD card (GitHub server address settings, all graphics, long button press time, maybe language ?)

I'll take a peek at that segueing you did in my free time because it's also a super thing very much needed.

As for the need to put button support in, I'm also thinking of adding them back in. I have no idea how to continue to operate this with just encoders, I thought about it but the code would get terribly convoluted and not very readable and error prone. Maybe use a joystick type switch? I should be able to find one at my place so I'll try to add it, I'm also thinking of adding an IR receiver to some sort of remote control- I'm going to have to go with the remote from my Technics in this regard as it has everything I need to operate it. As for the EN language version, it's actually time to give this some serious thought, why don't you take it up?

edit.
I managed to add a joystick, I created an additional void handleJoystick() function under its handling. For now I've done switching from the extreme X-axis positions of the radio stations one forwards and backwards each, tomorrow I'll add this functionality to the file player for testing. As for the revision of the version on github, for the time being, when something comes out, I immediately synchronise it to github, the changes are then visible in the commits:

https://github.com/sarunia/ESP32_radio_player...mmit/eba3d0c6494e286d0b3b59579d7268f65c525314

I had a regular joystick:


.

I changed the names to English. I have reworked the menu a little bit in the style of station selection and added the radio in the exit function after idle so that it exits the menu correctly.
Otherwise, when you enter the menu, turn to Player but do nothing, the radio goes dead. You cannot change the station.

currentOption = INTERNET_RADIO;
displayRadio();

What I have done in the player is that at the top, if the name fits, it prints the folder name plus the track number and if it doesn't fit
I cut it off and add three dots. Cosmetic, but nice to look at.

@MAJSTER XXL, do you also have problems with large FLAC files ? I have ones of 30 and 100MB and already with the 30MB one I have a problem - it doesn't play for me.

I'm not convinced about the joystick. It is very difficult to implement it into the case. I have never seen a nice solution to this problem.
Probably buttons would be better. E.g. something like in the attachment or just move the functions to buttons in one row.
It's always easier to get a tact switch and print a place for it. What do you think about this ?

IR remote control as much as possible YES.

welcome!
first of all, many thanks for such a nice project! i just started the build and i have a problem. version v1 i fired up without a problem, but in v2 i cant run. The code loads without a problem, but my display does not work. What could be the cause?

@atu1981 Have you re-soldered the jumper to the one marked?


.

@robgold Under what name to look for such a cool switch (5x tact switch), after the graphics it just sends me somewhere far east? I haven't checked large flac files, I'll look for some later and let you know. Today, I've mastered the joystick jump to the file being played one forwards / backwards. Backwards is complicated because you have to rewind the directory to the beginning of root.rewindDirectory() and in the next loop jump to the appropriate file. I have to additionally desensitise the joystick because sometimes it will flip "left" on its own.

I have the jumpers set to 4SPI. That is, the resistors at the locations of R5 and R8.

This is what the connection looks like to me. What is wrong?

@atu1981 .
And in the correct places did you connect it to the ESP ? The schematic is a bit confusing because it suggests the bottom of the PCB.
Have a look at the pictures I took of it for you quickly. On the first one you have the location relative to the ESP where the display plugs in. In the second and third you have the connection to OLED 3.12 and the jumper configuration.

By the way, I'm testing a small 2.08-inch OLED with the SH1122. It's not bad looking. It will eventually be in one of my versions.

I have already seen these buttons a few years ago from "colleagues" from the east on Electronics. I don't even know if TME doesn't sell them now.

>>21376653 Arthur, now I saw that you only have the display plugged in.
From a certain version of the ino file at the master, the radio will not run without the card plugged in. You will only get a message on the serial.
I additionally in my version initialise the OLED beforehand precisely so that the user gets a feedback message.

@atu1981 Post a screen from the serial terminal, we'll see where you are with the program. Personally I prefer to power this OLED from 5V, it needs a bit of current, I don't know if from the USB of the computer it will go-even I didn't have the idea to test with a USB-only power supply.

Master, it will work with 3.3V from ESP.
Admittedly, if you light a lot of pixels, you can see that the inverter on 18V slightly squats, but it works.
I "chase" mine like this and power the whole thing from a USB port with 500mA .

program, downloaded directly from github without any changes or corrections. To check the correctness of the board-display connection, I uploaded a sample sketch to this display assigning the no. as from the project and as you can see it works....





How do I get the terminal screen? - soryy i am not that advanced ;-(

@Majster XXL - screen shot of my settings and monitor data.

.

@robgold - after uploading this code there is progress! The display is working. We know the connection is ok. Just why is the right program in me working? Is something missing? or do I have the wrong settings?


.

Upload this:
https://github.com/dzikakuna/ESP32_radio_evo2

...and paste what is displayed on the OLED. I've set up a GitHub, this is the evo2 version of my interpretation of the code for this radio.
Info for those who are interested .

As for me, you are missing the SD card and since a certain version it has become crucial. Without it, the radio won't work at all because stations and station links are stored there.

After uploading your code, what I was waiting for appeared .




Actually I have to add a card because there is no station.



I will keep you informed. And already thanks a lot for your help gentlemen !!! And for improving the mood !

Thanks and flowers to the Major. I only distribute drinks at this banquet .

I still have an evo1..it's the last one that seems to run without a card, when I check I'll send you then you can test it for yourself before adding a reader.

Of course Majster has done a great job here.... nobody can deny it and all credit to him .
meanwhile after connecting the card.... I obviously have another problem . The stored music files read perfectly from the card, but the radio does not work:-( .


.

It should pull the bank file from the server when you apply power and it detects it is missing. Hold down the encoder knob and change the bank to any bank to force it to be read.

You are a champion! After holding down the encoder it pulled up the station. Thanks again for your help and time!!!
